To 60% whom it may concern.-

Be it known that I, ASHER ABRAM BROWER, a citizen of the United States,residing at Creston, in the county of Union and State of Iowa, haveinvented certain new and useful Improvements in Carpet-Stretchers; and Ido hereby declare the following to be a full, clear, and exactdescription of..the invention, such as will en able others skilled inthe art to which it appertains to make and use the same.

This invention relates to carpet-stretchers;

- and it consists in the novel construction and combination of the partsherein after fully described and claimed. r

In the drawings, Figure 1 is a side view of the carpet-stretcher, andFig. 2 is a plan view of the same from'above.

A is a bar provided with ratchet-teeth a on its upper surface andguide-grooves a in its sides.

Bis a prong secured to one end of the said bar and adapted to be driveninto the floor close to the wall.

0 is a cross-bar provided with the inclined points 0, adapted .to engagewith the carpet, and D are short guides secured to the bar 0 on eachside of bar A and engaging with the said guide-grooves; E is a loophaving its ends secured to the cross-bar O and adapted to engage withthe ratchet-teeth, so that the cross-bar cannot -slip back.

F is a hand-lever provided with a forked lower end f, which end isprovided with holes f aboutthe middle of its length, and is journaledupon the loop E on each side of bar A.

The device is double-acting. By moving the hand-lever in the directionof the arrow in Fig. 1 the loop G is caused to push against theratchet-teeth, and the cross-bar is dragged forward until the roller h,by meeting and pressing against the under side of the bar A, causes theloop E to engage with the ratchet, and thereby prevents the cross-barfrom slipping back. The hand-lever is then moved in the reversedirection from the arrow in Fig. 1, the looped pulling-pawl H engageswith the ratchet, and the cross-bar'is again dragged forward. The deviceis thus operated continuously by moving the hand-lever in oppositedirections alternately. The weight of the hand-lever and the other partsconnected to it is usually sufficient to cause the loop E to engage withthe ratchet; but at the termination of each full stroke of thehand-lever the roller it forces the said loop into gear, so that thedevice cannot let the carpet slip back. The roller also prevents thehand-lever and its pawl from rising too high and throwing too great astrain upon the short guides which slide in the grooves in the sides ofbar A, and only permit the cross-bar to have a limited rocking motion.The side arms 6 of loop E are elastic, and, together with the shortguides 'D, permit the cross-bar C to have a rocking motion, so that thelever F may rise and the loop E clear the teeth of the ratchet. The saidside arms e are preferably crossed under the ratchet-bar and connectedby the ring 6. This ring runs against the under side of the rack-bar andprevents the loop from rising too far.

What I claim is- 1'. In a carpet-stretcher, the combination, with aratchet-bar, the sliding cross-bar, and the short guides permitting thesaid cross-bar to have a slight rocking motion, of the pivotloopengaging with the ratchet-teeth and provided with elastic side armssecured to said cross-bar, the hand-lever pivoted on said loop, thepushing-pawl pivoted to the hand-lever above the ratchet-bar, and thepulling-pawl pivoted to the hand-lever below the ratchetbar,substantially as and for the purpose set forth.

2. In a carpet-stretcher, the combination, with the ratchet-bar, thesliding cross-bar, and the short guides sliding in grooves in theratchet-bar and permitting said cross-bar to rock slightly, of thepivotloop engaging with of the fork of the hand-leverbelow the ratchet-[O the ratchetteeth and provided with elastic bar, substantially as andfor the purpose set side arms crossed underneath the ratchet-bar forth.and secured to the said cross-bar, the ring In testimony whereof I affixmy signature 5 journaled 011 said crossed arms, the hand-lever inpresence of two Witnesses.

pivoted on said pivot-loop, the pushing and ASHER ABRAM BRO\VER. pullingpawls pivoted to the said hand-lever Witnesses:

above and below the ratchet-bar, respectively, \V. G. P. MUNBENDARA,

and the roller journaled between the prongs L. G. TOWNE.
